Avbob policy

I have been having money deducted from my persal payslip at work as I work for the department of Education in Kwa Zulu Natal. This has happed for a few months. Upon receiving my payslip and I went through it, I discovered that there is an amount of 247 that is being deducted by Avbob of which I do not know anything about. I never join and instructed AVBOB to debit from payslip.

This has been going on for a few months.

I do how ever have a policy with Avbob that I have had for many years that is debiting of my mother bank account. I even checked if the policy numbers were the same and they are not the same.
